General description

ANSA (8-Anilino-1-naphthalenesulfonic acid) is a hydrophobic polarity sensitive fluorescent dye useful as a site probe to detect conformational changes in cell and micelle membranes and molecules such as proteins. ANSA is also used as a fluorescent probe for the estimation of the critical micelle concentration (CMC) of surfactants.

The interactions between Urinary Trypsin Inhibitor (UTI) and 1-anilino-8-naphthalene sulfonate (ANS) were investigated by fluorescence spectra, isothermal titration calorimetry and molecular modeling. The results revealed the presence of four specific binding sites for ANS on UTI, with interactions driven mainly
